En las prensas hasta ahora conocidas de este tipo el dispositivo de empuje utiliza una serie de paquetes de muelles en forma de taza que presionan el balancín contra la excéntrica central con una elevadísima precarga elástica. Esta solución presenta un serio inconveniente: en el caso de rotura de uno o más de los muelles de taza de la serie de paquetes, el dispositivo de empuje está expuesto al riesgo de encallado cuya consecuencia es la aplicación al balancín de una carga variable, de todos modos no de acuerdo con la proyectada, con el riesgo de excesivas solicitaciones que pueden provocar desgastes precoces y de cualquier manera un funcionamiento no óptimo de la prensa.In presses known until now of this type The pushing device uses a series of spring packages cup-shaped pressing the rocker against the eccentric Central with a very high elastic preload. This solution It presents a serious inconvenience: in the case of breakage of one or more of the cup springs of the package series, the device thrust is exposed to the risk of stranding whose consequence is the application to the rocker of a variable load, however not of according to the projected, with the risk of excessive solicitations that can cause early wear and tear Either way a non-optimal operation of the press.

El objetivo de la presente invención es evitar dicho inconveniente.The objective of the present invention is to avoid said inconvenience.

Según la invención, dicho objetivo se alcanza gracias al hecho de que el mencionado dispositivo de empuje está constituido por un gato hidroneumático de alta presión.According to the invention, said objective is achieved. thanks to the fact that the mentioned pushing device is constituted by a high pressure hydropneumatic jack.

Gracias a esta idea de solución se elimina el empleo de los tradicionales muelles en taza, asegurando por la vía completa operativa de la prensa la constancia de la carga aplicada entre el balancín y la excéntrica central del árbol de levas, a fin de eliminar los inconvenientes descritos anteriormente.Thanks to this idea of solution the use of traditional cup springs, ensuring the route Full press operation proof of applied load between the rocker and the eccentric central camshaft, in order to eliminate the inconveniences described above.

La invención se describirá ahora detalladamente con referencia a los planos anexos, proporcionados únicamente a título de ejemplo no limitativo, en los cuales:The invention will now be described in detail. with reference to the attached plans, provided only to non-limiting example title, in which:

- la figura 1 es una vista esquemática en sección vertical que muestra la parte de una prensa mecánica para la producción de tejas según la invención correspondiente al árbol de levas para el accionamiento del compresor,- Figure 1 is a schematic sectional view vertical showing the part of a mechanical press for the production of tiles according to the invention corresponding to the tree of cams for compressor drive,

- la figura 2 es una vista en sección transversal según la línea II-II de la figura 1, y- Figure 2 is a cross-sectional view according to line II-II of figure 1, and

- la figura 3 es una vista en sección transversal según la línea III-III de la figura 2.- Figure 3 is a cross-sectional view according to line III-III of figure 2.

Para la simplicidad de la ilustración, los planos anexos representan solamente la porción de una prensa mecánica para la producción de tejas que se refiere concretamente a la presente invención. Por otra parte la conformación general de la prensa es totalmente convencional y por tanto bien conocida por los expertos en la materia. Es sin embargo oportuno aclarar brevemente que la prensa está constituida por una estructura de soporte que incluye dos flancos unidos por una base y por un arquitrave. En la zona inferior de la estructura de soporte está dispuesto en forma giratoria un grupo portamoldes inferior, normalmente constituido por un tambor con seis caras, el cual gira entre los flancos de la estructura de soporte accionado por una estrella en cruz de malta.For simplicity of illustration, the plans annexes represent only the portion of a mechanical press for the production of tiles that specifically refers to the present invention. On the other hand the general conformation of the press is totally conventional and therefore well known to experts in the matter. It is however appropriate to clarify briefly that the Press consists of a support structure that includes two flanks joined by a base and an architrave. In the zone bottom of the support structure is arranged in shape rotating a lower mold carrier group, normally constituted by a drum with six faces, which rotates between the flanks of the support structure operated by a cross star of malt.
